Thermal drone surveys: what can they actually show?
Understand what a thermal image measures, what it cannot prove and how to commission useful analysis rather than a colourful picture.
Published price examples, the reasons quotes differ and a practical way to compare the full cost of a drone assignment.

There is no single meaningful price for a “drone job”. A short image-capture visit, an interpreted building report and a controlled engineering survey involve different work. Price ranges are useful for setting an initial budget only when the scope attached to them is clear.
For example, Full View’s published roof-inspection cost guide gives starting figures of around £400 for residential drone work and £700 for commercial properties. Skykam’s survey-grade pricing article gives £1,200–£2,500 excluding VAT for a small topographic survey, with control, checking and CAD deliverables in its example scope. These are two providers’ published illustrations, checked on 9 October 2026—not quotations from this website or a market-wide price study. Ask each supplier to confirm VAT and your actual specification.
Our recommended comparison separates preparation, attendance, processing and interpretation. Preparation covers understanding the site and planning the job. Attendance covers the crew and capture. Processing makes the photographs or sensor data usable. Interpretation turns observations into a professional opinion where that is part of the commission.
Ask the provider to identify which stages are included, even if it charges a single fixed fee. For a roof, “images of all visible slopes” is a different promise from “an annotated condition report reviewed by a surveyor”. For filming, a set of raw clips is different from a finished film with music, captions and agreed revisions.
Use a short checklist rather than choosing from the headline totals. Write the same address, site extent, purpose, required outputs and deadline at the top. Then ask both suppliers to confirm coverage, deliverables, exclusions, turnaround and the total payable. A blank answer is a question to resolve, not a saving.
As a hypothetical example, an image-only quotation may look cheaper than one that includes an interpreted report. If your property manager needs a report to instruct repairs, the first quote may require a second commission. The fair comparison is the cost of reaching the same usable result, not the price of getting a drone into the air.
Send photographs of the site, an accurate address or boundary, access details and a sample of the output you want. Ask your eventual data user—such as a designer, surveyor or marketing colleague—to approve the specification before booking. Changing the deliverable after capture can create avoidable work.
Do not reduce a technical survey budget by silently dropping accuracy checks, or reduce an inspection budget by assuming every hidden area will be visible. Instead, ask which parts of the specification are essential for your decision and which are optional. A responsible provider should be able to explain that distinction.
Confirm who your contract is with, what happens if the visit cannot proceed, when the final files arrive, how long you can access them and what process applies if the agreed outputs are incomplete. For repeated visits, ask whether the fee is per visit, per completed dataset or part of a longer commitment.
The cheapest suitable quote may still be the right choice. What matters is that you have established suitability first. Keep the agreed scope with the quotation so that both sides can check delivery against the same requirements.
Only if the deliverables and included work are also comparable. A lower day rate can still lead to a higher overall bill if processing or interpretation is extra.
No. The figures are named providers’ published examples checked on the research date. Obtain a written quote for your site and confirm tax and inclusions.
